The Telescopic Frame Adapter bolts around the trailer frame to create an alternative connection point for our trailer dollies. These universal frame adapters are designed to fit the most common trailer frame heights, with two models available for light and heavy-duty towing. Install the adapter on the trailer’s A-frame or directly onto the trailer tongue if space allows. No welding, drilling, or cutting required!
Ensure the model you select is compatible with your trailer dolly. Measure the overall height and width of the installation point on your trailer frame to confirm the fit. Make sure to stay below the maximum weight capacity of your trailer dolly!
Not sure which model is best for your trailer? We recommend:
1 x Adjustable Adapter Tube with 3/8" Quick Pin (3/8” x 2 3/4” long)
1 x Adapter Plate
4 x 3/8" x 4" Bolts
4 x 3/8" Nylon Nuts
Installation Instructions:
Level out the trailer and secure it in place with wheel chocks.
Remove the Telescopic Pipe, then bolt the adapter around the trailer frame with the included hardware. Use the hole configuration that best fits the height of the trailer frame. When installing, ensure the lower Telescopic bolts are flush with the base of the trailer frame. Tighten with a 9/16” wrench and socket.
Once secured, move the dolly underneath the adapter. Align the adapter with the dolly’s receiver tube, then drop the Telescopic Pipe through the adapter and into the dolly.
Secure Telescopic pipe height with the included pin, then lower the trailer onto the dolly and go!

Yes!Each trailer dolly includes a hitch adapter that's compatible with most ball mount trailer couplers. See the Transformer, Carrier or Accessories page for additional connections. All electric models include batteries, charging cables, hardware and built-in safety features so you can park with confidence.
GVWR (Gross Vehicle Weight Rating) includes the capacity of your trailer (how much you can put in it, including passengers). This is different from the dry weight, or unloaded vehicle weight (UVW), which is the weight of your trailer when empty.
Tongue weight is the downward force that the trailer tongue applies to the hitch when connected to the trailer dolly. Using your Parkit360 for a trailer with too much or too little tongue weight could make moving and steering difficult, or cause issues with traction. We recommend that your tongue weight be 10% of your trailer's gross weight (GVWR), although this may vary for smaller trailers.
If you are not completely satisfied with your Trailer Dolly, customers in the Mainland US and Canada can return their unit up to 30 days after receiving their dolly for a refund, minus a flat return shipping cost and restocking fee.
Parts Only and International Trailer Dolly orders are not eligible for return.
